You have to find fresh fungi with stems that are intact. The stems are required for breeding. So while picking up edible fungi choose the ones with perfect stems. If you cannot find living stems or you are hesitant about the quality of local mushrooms whether they are poisonous, then go in for pre-made oyster mushroom spawn for sale. Mycelium helps in producing mushrooms under proper conditions. So make and nurture your spawn to produce quality mushrooms.

Multiplying:

Fill a big bucket with lukewarm water. You can make mushrooms proliferate with cardboard. While making a selection of cardboard, use the ones from those countries which do have environmental regulations. Avoid those cardboards which have toxic glues. Soak the cardboard pieces into this warm water for several hours. Drain the water and tear the cardboard layers to show the corrugated area. Place these back into the bucket and add the mushroom stems or pre-made spawn. Cover with extra cardboard. Keep them in the dark place. This process will take a few months. The spawn once it has multiplied, will be ready when you see a whitish coating on the box.

Planting:

When the spawn is ready for use, a substrate can be inoculated. Moisten and keep in a cool, dark place.
